'Description' => %q{
|
|
The NVRmini 2 Network Video Recorded and the ReadyNAS Surveillance application are vulnerable
|
|
to an administrator password reset on the exposed web management interface.
|
|
Note that this only works for unauthenticated attackers in earlier versions of the Nuuo firmware
|
|
(before v1.7.6), otherwise you need an administrative user password.
|
|
This exploit has been tested on several versions of the NVRmini 2 and the ReadyNAS Surveillance.
|
|
It probably also works on the NVRsolo and other Nuuo devices, but it has not been tested
|
|
in those devices.
